Achieving Interoperability Using Open Standards and Specifications David Danko, Marten Hogeweg, Esri Abstracting geographic knowledge

Visualization, Encapsulating Analytics, real world Decision support. . . knowledge

Models Maps Geodata Metadata GIS interoperability – exchanging and using geographic knowledge

Interoperability: the ability of two or more systems or components to exchange information and to use the information that has been exchanged *

Technical interoperability Semantic interoperability * IEE Abstracting unlimited variety of features/phenomena GIS - merging diverse information

Diverse: information types formats location reference systems perspectives Distributed Integrated by location

Interoperability enablers Infrastructure

• The bad news – whew, a lot of standards - Many organizations feel their needs are special - Politically feel the need for an exclusive approach - As a broad based GIS provider Esri is involved a larger number than most • The good news - There is overlap! - Some standards are foundations for others - Esri doesn’t need to implement all - Some are mainstream IT standards - Esri is very active in getting SDOs to work together - Interoperability is working  Full list of Esri implementing, compliant, and reference implementations
